A fast turn-off and fast turn-on circuit (10) providing at least one power source (12, 20), at least one switching device (14, 22), a coil (16), and at least a first voltage control device (18). The at least one switching device (14, 22) is connected to the at least one power source (12, 20) for selectively connecting the at least one power source (12, 20) to portions of the circuit (10). An electrical current from at least one power source (12, 20) charges the coil (16) and creates an electromagnetic field when the at least one switching device (14, 22) is in a closed position and connects the at least one power source (12, 20) with the coil (16). The first voltage control device (18) limits a voltage in the circuit (10) when the electromagnetic field decays. |
